Hi all, My DWC (5gal bucket) temps rose too high a couple weeks back when my A/C blew, and it looks like I’m dealing with root rot based on slimy brown spots on some roots, while others are pearly white, plus my pH crashes down into the 4s about every 24 hours. I’ve been doing research on using...

I followed a similar approach, experiencing rising EC and falling pH. Chart says res change and lower EC. I did that all the way down to 0.6EC with the same results (only worse b/c some of the plants then started showing signs of nute deficiencies). I ended up raising the EC back up to around...

Just as a point of reference, here are the trichs on the other strain that I think is further along

OK, so lately I've been dealing with deciding when to harvest. Recall, there are two strains in the same res. The one that has given me less trouble (the more indica-looking one) has the classic signs of being in the harvest window - white trichs, all red hairs curled in, etc. The other...

Still waiting on the trichs to finish up. Looks like they're getting better (see attached). 11.5 weeks since the flip...

OK, so in this one I have circled in blue which bud the pics came from. Supposed to be indica-dominant hybrid, but it's long and lanky like a sativa. The shorter, bushier ones with thick buds up the colas are the other strain that has the white trichs, etc.

So I dunno if this will help b/c the pics aren't that great. I have about 5 reasons I don't want to turn off my LED, and I don't have a filter for my phone to make the colors true up, so purple it is... First two pics are the nug from which the above trichome pics were taken (with a digital...

I guess I was referring to Flower as a stage - like you're either in veg or you're in flower, so I guess technically 63 days from flip.

Thanks, yeah one of my four plants has trichs like that, with 100% of pistils are bown and curled. Another has mostly cloudy trichs but the other two are like what I posted above.

Yeah, thanks. So I'm basically asking peoples' opinion if these are half-clear/cloudy or if they are clear. Your middle chart with the red X and three green checks/ticks says half-clear is good to harvest and gives a more "speedy" high, which is fine with me. I'm just on the fence about...

First-time grower, but studying hard. Long-story, short: Day 63 of flower and I have four plants (different strains - won't do it again) sharing the same res (DWC, RO water) and half are definitely ready for harvest with solid-white trichs, but the other half I'm not sure. My grow tent will...

In case someone is following this to fruition: cal/mag was a big help. I did not know I needed to add it to my RO water - I thought it was optional, but for me it was not. My pH drops only fell into the 5.2-5.4 range after that adjustment. Still something going on, but manageable - I think...

For anyone tracking this, my gains have been short-lived. I am able to stabilize the pH for up to 36 hours after adding Great White and hydroguard (hydroguard alone appears to do nothing - maybe it keeps things from getting worse). Do people who use GW add it when they top-up? I've been...

Two Part Update: Purpling: Attached is a photo I snapped today that shows the negative outline where a fan leaf was laying across another fan leaf. Where the fan leaf covered the lower one, the lower one is green (but otherwise all purple). That makes me think it's tied to the light. It also...

Good question. I'm definitely running at higher temps.

Yeah, sorry I meant to post that data. Temps range between 75-86F; RH 55-65% (up to 72% once when my dehumidifier filled up). It's toasty in there, I don't think it's low temps. Will keep an eye on 'em Day 26 of Flower for point of reference

Here's some data on the purpling issue - not sure if related to pH drops, EC spikes. This only happens with one of my two strains. They are both supposed to be indica-dominant hybrids, but one is short and bushy (indaca-ish) and the other tall and lanky (sativa-ish). This is the taller...

Changed out the res today - here's a pic of the roots in a near-empty res. To me, looks like some slight staining but a little slime here and there too... This res change I went to 0.95EC; pH 6.2 w/ RO water, cal/mag, nutes, 2.5ml/gal hydroguard, Great White @ about 0.75g/gal. - in that order...

So, both the cal/mag and the Great White have a dark tint to them which takes my otherwise essentially-clear nutrient solution more brownish than otherwise. But I do think I have a pythium issue, and while there isn't a ton of slime I think I can see some. Interestingly, the others don't seem...

So that was short lived... 9pm numbers were good (see above), by Noon the next day EC was up to 0.86 and pH down to 4.8. If Great White did anything, it was over in less than 24 hours... I'm seeing purpling of the fan leaves on some of my plants (all the same strain) - not sure if it's a K...
